Who should consider the Lunar Lexon 640 RS?
Who it suits
- Couples wanting a spacious four-berth layout with a fixed bed and a substantial rear washroom.
- Buyers who can accommodate a twin-axle caravan and want the interior space associated with its 7.95-metre length.
- Tourers who value Alde heating, a separate shower cubicle and a front sky-view window.
- Small families needing four berths, provided the recorded payload is sufficient for their equipment and belongings.
Reasons to consider it
- The fixed transverse island bed gives the sleeping area a defined place within the layout.
- The full-width rear washroom and separate shower cubicle provide more washroom space than a compact end-bathroom arrangement.
- The twin-axle design supports the caravan's large footprint and is identified as a strength for towing stability.
- The recorded kitchen equipment includes a Dometic fridge-freezer and Thetford Aspire oven and grill.
- Storage is described as including under-bed space and large overhead lockers.
What to check
- Confirm that the tow car is suitable for the caravan's 1500-kilogram MTPLM and twin-axle configuration.
- Measure storage and pitch access against the recorded 7.95-metre length, 2.33-metre width and 2.63-metre height.
- Calculate the loaded caravan weight carefully because the listed payload is 159 kilograms.
- Check the transverse bed, adjustable headrest, shower cubicle and washroom fittings in person.
- Verify the condition and operation of the Alde heating and hot-water system, kitchen appliances, corner steadies and any motor mover fitted to the individual caravan.
Worth knowing: The supplied information does not identify a production year, so age and specification require confirmation from the individual example. The description refers to lightweight construction, but the recorded dimensions and twin-axle layout still require careful tow-car and site-access planning. Price information is a range rather than a valuation of any particular example.

The allowed alternatives include shorter four-berth models, while some have higher recorded MTPLMs or different listed price ranges. The most suitable choice depends on tow-car capacity, payload needs, available storage and the importance of the Lexon 640 RS layout.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership checks for the Lunar Lexon 640 RS
- Plan loading around the recorded 159-kilogram payload, including personal equipment, fluids and fitted accessories.
- Use the caravan's 7.95-metre length and 2.33-metre width when checking storage, pitch access and manoeuvring space.
- Allow for the 2.63-metre height when assessing covered storage and low-clearance routes.
- Keep weight distribution considered across the twin axles and follow the caravan and tow-car guidance when loading.
- Check the fixed transverse bed, under-bed storage, overhead lockers and rear washroom regularly for movement, damage or water ingress.
- Test the Alde heating and hot-water system, Dometic fridge-freezer, Thetford Aspire oven and grill, shower and corner steadies as part of routine ownership checks.
Common mistakes to avoid
- Treating the four-berth capacity as evidence that the 159-kilogram payload will suit every family load.
- Overlooking the access and manoeuvring implications of a 7.95-metre twin-axle caravan.
- Assuming all examples share the same equipment when specifications may vary by model year, trim and optional equipment.
Worth knowing: No specific fault pattern is supplied, so these are checks rather than claims of known defects. Service requirements and component condition depend on the individual caravan and should be confirmed with appropriate records or inspection.
